DT Series Traffic Signal Module – Arrow

Name: DT Extended-Life LED Traffic Signal Arrow | LEOTEK
Brand: LEOTEK

Availability varies by configuration; see the specification sheet.

The DT Series extended-life 12-inch LED traffic signal arrow supplies red, yellow and green directional indications for compatible signal heads. Its dedicated thermal and power-supply design targets longer replacement intervals for municipal and DOT signal assets.

The DT arrow specification lists 80–135 Vac operation, 6 W red, 10 W yellow and 6.8 W green model draws, Intertek ETL verification and a 15-year limited full-performance warranty. Match indication color, lens option and housing to the selected order code.

Application & design reference

Right-turn modes: check the face before selecting a module

The lane, complete face and operating mode determine which message an arrow must communicate. Use the approved design, then verify the exact module and control interfaces.

FHWA Figure 4F-9: Typical Position and Arrangements of Separate Signal Faces with Flashing Yellow Arrow for Permissive Only Mode Right Turns. — FHWA, MUTCD 11th Edition with Revision 1 (December 2025), Figure 4F-9, printed p. 695 / PDF p. 736. Original figure and provisions. Select the image to read the full-resolution notes.

A separate permissive right-turn face

Figure 4F-9 shows a flashing-yellow-arrow arrangement for permissive-only right turns. Section 4F.11 requires a mandatory right-turn lane for a separate face and does not permit a circular green indication in that face during the mode.

Keep the steady/flashing legend and red-indication note with the arrangement. Where a circular red can be seen by through drivers while their faces are not red, the stated sign or visibility-limitation provision matters.

The drawing does not establish that every yellow-arrow module supports the illustrated functions. Verify the exact model, input, functions and compatibility for the project.

Original figure and provisions. Select the image to read the full-resolution notes.

Protected/permissive and variable operation

Figure 4F-14 distinguishes protected green-arrow and permissive flashing-yellow-arrow displays. Its asterisks identify indications suppressed in particular modes. Preserve those qualifications when comparing configurations.

A steady photograph cannot verify flashing behavior or the transition between modes. The submittal should identify the complete face, controller configuration, pedestrian and vehicle conflicts, and required compatibility evidence.

Read the complete right-turn guide with four MUTCD arrangements.

Does selecting a yellow-arrow module create a flashing-yellow-arrow installation?

The module is one component. Verify the required functions, complete face, controller, wiring and compatibility. A model listing or a matching opening does not establish the entire operating sequence.

Can the same diagram be applied to a combined through/right lane?

The separate-face provisions require a mandatory right-turn lane. Combined lanes have their own restrictions under Section 4F.09; do not transfer a separate-lane arrangement without the design review.

Does bimodal mean every unit provides the same functions?

No. Identify the particular steady, flashing and color functions required. Obtain documentation for the proposed configuration and its electrical/control interface.

Are these LEOTEK model-specific wiring instructions?

No. They are original MUTCD application figures. Use the approved project design and the exact equipment documentation for installation, operation and acceptance.
